G4X EVOLink 4-8 (AN Temp 4)

[kfaz123]

 

Hi I have a question regarding AN Temp 4 input on a G4X EVOLink 4-8 plugin ECU. I have attached the pin out for the plug-in ecu bellow it does not have a pin listed for AN Temp 4 though this input is listed as an available input in PC Link when connected to my ecu. I am just wondering if this is actually connected to a pin on the ECU and not listed or this temp input is not available on this ECU. If it is not available for use on this ECU I will just use a AN Volt input with a external pull up resistor for the temp sensor i will be connecting. I am already using AN Temp 1 thru 3 for their listed pin outs bellow. This ECU is running in a EVO 6 using modelled fuel equation.

Yes, unfortunately ANT4 is not connected to an externally available pin on this ecu.  It will have to be a volt input with an external pull up.

Thank you for the quick reply this is what I figured just thought I would ask.

Thx Again!

I noticed An temp 4 labelled on the board adjacent to one of the CAN plugs, can this be utilised, ie direct connection to the board pin or is it used for an ECU temp or something?

It would work but modifying the board will void your warranty.

Thanks for that. Will leave that in mind for future if I run out of inputs.
